In the first week of October 1932, an International Conference on Migration Statistics was held in Geneva. Over the course of five days, some thirty statisticians from twenty-six countries discussed how to produce more reliable international migration statistics. This kind of methodological discussion about statistical standardization was not at all unusual in the new world of international organization. Since 1920, the standardization of statistics had become an ordinary activity in the “Palace” of the International Labour Organization and the League of Nations in the hills above Lake Geneva.
The International Conference on Migration Statistics offers particularly interesting insights into the historical attempt by international organizations to measure the world. On the one hand, “international migration” was not yet a category in scholarship and policy making. It was an international invention intended to bring together the existing categories of “emigration” and “immigration.” Before this time, these last two categories were perceived as two fundamentally separate phenomena. Perhaps more plainly than other objects targeted by statistical analysis, “international migration” was connected to the effort to construct a new international understanding of the world after the Great War.
